1.I have been having a lot of performance issues that I thought was due to virus or malware..have run several tools in safe mode.&/or .system restore disabled..nothing found..bought PC Advisor from Parotologic was supposed to correct the 400 registry errors it found and make me "more healthy" and paid for them to take over and maximize my PC. Helped some but they found no virus with their tools either.when trying to look at Stinger"s .opt file box said couldn't open .opt (earlier something said I couldn't open .dll files and wanted me to buy something... Microsoft sent back to buy PC Advisor again or a couple other registry fixers(pc advisor hadn't worked) ..(.Is there a free registry fixer?) while preparing to use Malwarebytes virus tool..site said to first run Registry Mechanic... it found 935 registry errors and said my system was very unhelathy.& for 29.95 they'd fix it. The registry errors appeared to be almost all in the PROGRAMS files..(some were in add/remove programs) Tried to do defrag in safe mode..after running klez and finding no infection.. defrag wouldn't start by double clicking nor rt.click and clicking run nor run as administrator..should that happen???How important is it to fix these errors and to be able to open .opt and .dll files? The registry errors are causing performance problems aren't they????
2. McAfee Security center running in Vista on my Dell Inspiron is acting really wierd..whole system has slowed down too..for a month or so (why I've suspected infection) and I found the "quarantined potentially unwanted programs" to be full of cookies when I finally found it & opened it..(dated since june)..a zillion of them..took forever to open and when it finally did, after NOT RESPONDING a lot & saying"this program is running a script that is causing In.explorer to respond slowly" task manager would show running for couple seconds then not responding couple seconds back and forth..Finally they all loaded in the box..I hit "select all" which took forever to hilite, then I hit delete and after a lonnnnnnng time they disappeared from the box..but status wheel was still spinning...stopping ...spinning... stopping.Went back in later and the darn cookies are still there..Do you think McAfee is infected(hiding really well cause about 6 tools & multiple scans run showed no infection anywhere ) or corrupted?? I've got the McAfee disk that came with the puter..I looked in program files to see if I could find the folder that holds the quarantined potentially unwanted programs with the thought that I'd delete them there, but couldn't tell what folder they were in..Right now I'm trying to bring up the quarantined p.u.p.s and it's freezing again and my cursor is blinking on and off.( No scan is running)..There was a file called "custom uninstall" in the program file that I think I had to use to completely get rid of McAfee once before,if I remember right(yes it says reinstalled 12-23-2008on the cover..wierd exactly 2 yrs ago). Do you think I should uninstall?? I had a notation in my log that I had called McAfee then.. Help please..again...and Happy Holidays.
